A few days ago I tried to press the home button on my Samsung I5800 Galaxy 3 but it didn't work at all I tired to clean the RAM to unchecked most of the settings or to try REBOOT but I couldn't reboot at all.After removing the battery or waiting or turning off and on the home button still didn;t work .Please help me to find a solution to thins HUGE problem.I haven't dropped it or hit it so it must be from the phone settings or a program software problem.If this is going to help I notice this problem after my phone battery died and after I recharged and turned it on it I notice that the button doesn't work at all.

That was terrific advice, Mary - Wow. FOR MONTHS I have been dealing with this and didn't ever notice or realize that HOME button. HUGE difference. Now if I can only ROOT my phone and get of all the useless junk on it. I hate that. How they slam useless apps that really busy people will never use. Ever. I wish all well ~

The problem is that I tried to reboot but I couldn't Somehow it doesn't work anymore..Also the flight mod is gone when I push the on/off button there is only switch off option...Every other option is gone..plus the home button problem :S

When did you buy the device? This sounds like you may have some faulty hardware. If your phone is still under warranty I'd recommend taking it in for a service in case it's a manufacturing fault. I take it you've tried a Factory Reset already and that hasn't fixed the problem? If not, the tutorial is here.

Well my bf bought it in 2011 at the beginning I think from ebay.I tried to Reboot I will try with what you have suggested I hope it works.Otherwise I have to wait until I find someone who knows something about devices and electronics and show it to him.Thanks for the advice.

Thanks a lot I deleted everything with the instruction you wrote and it worked ..I lost everything else , but it doesn't matter , at least the phone is back to normal.I guess it was all about the apps or just the phone sucks who knows

I'm glad the Factory Reset solved your problem. In future, just remember to back everything up before doing a Factory or Hard Reset, so you can reinstall all your apps, contacts and messages etc once complete. We have all the details in the tutorial. But as long as your device is working properly now and you're happy then I'm happy too.

I am afraid to instal any kind of apps . I think the main problem was because of them, so for now I will not instal anything at all..And thanks again HUGE and many thanks.I am really happy that I solve this problem , I wasn't using the phone so often or at all but still it good to know that is works without problems or bugs

No problem! If you'rte worried about apps being the cause of the problem you can install a secuirty app like Lookout to scan apps once you've downloaded them (before they install), or you can downloads apps on your computer and scan them with an anti-virus program before you transfer them to your phone. That will solve the vast majority of problems. Reading the most recent comments in the Play Store is usually a good way to know if a current version of an app is behaving itself or causing problems.

Thanks, that could come in handy.But with or without apps my phone is still slow and sometimes its stuck..Like I said thanks for helping me although I am not liking smartphones or using this one at all it is god to know that it is repaired.
